CONVERTIBLE LOOM Filed Jan. 21, 1949 2 Sheets-Sheet 2 INVENTOR. JOHNGERHARD EMANUEL KLAESSON Patented June 2, 1953 CONVERTIBLE LOOM J ohnGerhard Emanuel Klaesson,

Orebro, Sweden Application January 21, 1949, Serial No. 71,780 In SwedenJanuary 23, 1948 This invention refers to a loom which is convertibleinto a table.

The object of the invention is to provide. a handy and suitable loom,which, when not in use, in a simple manner can be converted into atable, making it possible to have and to use such a loom even indwellings suffering from alack of space. A great variety of looms,convertible into tables have earlier appeared on the market, but withmost of them the conversion has proven to be a difiicult task, andtherefore they have become rather impractical.

The loom according to this invention comprises two side pieces, betweenwhich a warp beam, a cloth beam and a breast beam etc. are arranged,said side pieces being at their rear and front ends respectivelyprovided with raised supports for a table top which is foldably attachedto the rear of said supports. The invention is mainly characterized inthat the batten, which carries the reed, is so arranged that, as thetable top is respectively raised or lowered, said batten isautomatically raised to its working position or lowered to a positionpermitting the table top to completely rest on the aforementioned sidepieces. This is preferably efiected by swingably journalling the battenin an intersection joint of a link system, so that when the table top isbeing raised, said batten is by means of a pulling bar, connected to thetable top, pulled up to a suitable elevation. The invention is furthercharacterized in that the pulleys of the shaft cords are placed at andunderneath the table top so that when the table top is raised up theshaft cords occupy their proper positions. When the top is lowered, theshafts are laid over the batten and thus, like the rest of the loomparts, they are protected underneath said table top. A small amount ofslack is given the warp so as to permit the lowering of the batten andthe table top.

The loom according to .the invention is thus ready for use by effectingtwo simple and natural operations, viz. the raising up of the table topand the stretching of the warp. The stretching as well as the slackeningof the warp is achieved by turning the cloth beam. The invention will bemore fully described below with references made to an embodiment shownon the attached drawing.

Fig. 1 shows a cross section end view of the loom with the table topshown in raised-up position, ready to be used for weaving;

Fig. 2 shows the loom with the table top in lowered position also in across sectional end view; and

7 Claims. (01. 139-29) Fig. 3 shows a perspective view of the wholemachine.

,The side pieces I are on their front and rear edges provided withraised supports Ia for'the table top 2, and held together by eitherspecial cross bars or with the aid of some of the beams. A warp beam 3,a stretch beam 4, a breast beam 5 and a cloth beam 6, are in a knownmanner arranged between said side pieces. The table top 2 is with itscross bars 1 swingably-mounted at 8 on the rear support la of the sidepieces. ,At each side of the loom just in front of the pivot point 8 apull rod 9 is pivotally connected at its upper end to the cross bar I onthe top 2. Said rod 9 extends inclinedly forward and downward towardsthe lower forward corner of the pertinent side piece, its lower endbeing hingedly connected to the lower end of anarm II carrying thebatten l0, and also to the lower, free end of a link t2, hanging downpivotally from'its respective side piece, said link being swingablyjournalled at [3.

Between the Crossbars l and a short distance from the fore edge of thetable top arod I4 is arranged, which carries the heddles l5. Thetreadles I6, which operate the heddles are placed in the usual mannerunder the loom and with the rod 16 complete the shed arrangement.

In order to secure the top 2 so as to remain in its raised-up, orelevated position a pawl I1 is attached to each of the side pieces, saidpawl being engageable with a notch in the pull rod 9 at the related sideof the machine. On each of the side pieces there is also a brace ill forthe batten l0.

When the top 2 is in its raised-up position, the links i2, on account ofthe pull exerted by the pull rods 9, occupy a backwardly directedposition, as in Fig. 1, and the batten is thus held in working position,in which the upper end of the batten will describe an arc entirely abovethe top edge of the side pieces at each stroke. The heddles [5 will thenhang practically plumb from the rod Hi.

When the loom is converted into a table, the top 2 is lowered after thewarp has been given a small amount of slack, so that the batten islowered to a location at which its upper edge is below the top line ofthe side pieces, and the shafts are placed over the batten, as in Fig.2.

The invention is of course, not limited to the embodiment shown on thedrawing, but a number of modifications are possible without deviatingfrom the original, inventive idea. Thus the raising or lowering of thebatten, effected by the th lewe $1 94 id k; n t e sta es-remitted tabmovement of the table top can of course be brought about by other meansthan those shown on the drawing. 'The table top may also be removable,leaving only the cross bars I to carry the pull rods 9 and the heddlesl5.

Having now described my invention, what I claim as new and desire tosecure Letters Patent is:

1. A "loom, which is convertible into a tabie, comprising two sidepieces, a number of loom beams arranged between said side pieces, atable top, pivot means pivotally mounting said ,table top mounted at therear upper end of both side pieces, and an erected batten mountedwithinsaid side pieces, said batten being elevatable from a storageposition, in which it ,is ,kept .belpw ,the upper edges of said sidepieces so as to permit said table top to rest thereon, into a workingposition.
